The Grand Duke had now only to prepare for resistance, and this he did with that determination and coolness of which, under other circumstances, he had given incontestable proofs. The news of the taking of Ichim, Omsk, and Tomsk, successively reached Irkutsk. It was necessary at any price to save the capital of Siberia. Reinforcements could not be expected for some time. The few troops scattered about in the provinces of Siberia could not arrive in sufficiently large numbers to arrest the progress of the Tartar columns. Since therefore it was impossible for Irkutsk to escape attack, the most important thing to be done was to put the town in a state to sustain a siege of some duration.

      The preparations were begun on the day Tomsk fell into the hands of the Tartars. At the same time with this last news, the Grand Duke heard that the Emir of Bokhara and the allied Khans were directing the invasion in person, but what he did not know was, that the lieutenant of these barbarous chiefs was Ivan Ogareff, a Russian officer whom he had himself reduced to the ranks, but with whose person he was not acquainted.

      First of all, as we have seen, the inhabitants of the province of Irkutsk were compelled to abandon the towns and villages. Those who did not take refuge in the capital had to retire beyond Lake Baikal, a district to which the invasion would probably not extend its ravages. The harvests of corn and fodder were collected and stored up in the town, and Irkutsk, the last bulwark of the Muscovite power in the Far East, was put in a condition to resist the enemy for a lengthened period.

      Irkutsk, founded in 1611, is situated at the confluence of the Irkut and the Angara, on the right bank of the latter river. Two wooden draw-bridges, built on piles, connected the town with its suburbs on the left bank. On this side, defence was easy. The suburbs were abandoned, the bridges destroyed. The Angara being here very wide, it would not be possible to pass it under the fire of the besieged.

      But the river might be crossed both above and below the town, and consequently, Irkutsk ran a risk of being attacked on its east side, on which there was no wall to protect it.

      The whole population were immediately set to work on the fortifications. They labored day and night. The Grand Duke observed with satisfaction the zeal exhibited by the people in the work, whom ere long he would find equally courageous in the defense. Soldiers, merchants, exiles, peasants, all devoted themselves to the common safety. A week before the Tartars appeared on the Angara, earth-works had been raised. A fosse, flooded by the waters of the Angara, was dug between the scarp and counterscarp. The town could not now be taken by a coup de main. It must be invested and besieged.

      The third Tartar column—the one which came up the valley of the Yenisei on the 24th of September—appeared in sight of Irkutsk. It immediately occupied the deserted suburbs, every building in which had been destroyed so as not to impede the fire of the Grand Duke’s guns, unfortunately but few in number and of small caliber. The Tartar troops as they arrived organized a camp on the bank of the Angara, whilst waiting the arrival of the two other columns, commanded by the Emir and his allies.

      The junction of these different bodies was effected on the 25th of September, in the Angara camp, and the whole of the invading army, except the garrisons left in the principal conquered towns, was concentrated under the command of Feofar-Khan.

      The passage of the Angara in front of Irkutsk having been regarded by Ogareff as impracticable, a strong body of troops crossed, several versts up the river, by means of bridges formed with boats. The Grand Duke did not attempt to oppose the enemy in their passage. He could only impede, not prevent it, having no field-artillery at his disposal, and he therefore remained in Irkutsk.

      The Tartars now occupied the right bank of the river; then, advancing towards the town, they burnt, in passing, the summer-house of the governor-general, and at last having entirely invested Irkutsk, took up their positions for the siege.

      Ivan Ogareff, who was a clever engineer, was perfectly competent to direct a regular siege; but he did not possess the materials for operating rapidly. He was disappointed too in the chief object of all his efforts—the surprise of Irkutsk. Things had not turned out as he hoped. First, the march of the Tartar army was delayed by the battle of Tomsk; and secondly, the preparations for the defense were made far more rapidly than he had supposed possible; these two things had balked his plans. He was now under the necessity of instituting a regular siege of the town.

      However, by his suggestion, the Emir twice attempted the capture of the place, at the cost of a large sacrifice of men. He threw soldiers on the earth-works which presented any weak point; but these two assaults were repulsed with the greatest courage. The Grand Duke and his officers did not spare themselves on this occasion. They appeared in person; they led the civil population to the ramparts. Citizens and peasants both did their duty.

      At the second attack, the Tartars managed to force one of the gates. A fight took place at the head of Bolchaia Street, two versts long, on the banks of the Angara. But the Cossacks, the police, the citizens, united in so fierce a resistance that the Tartars were driven out.

      Ivan Ogareff then thought of obtaining by stratagem what he could not gain by force. We have said that his plan was to penetrate into the town, make his way to the Grand Duke, gain his confidence, and, when the time came, give up the gates to the besiegers; and, that done, wreak his vengeance on the brother of the Czar. The Tsigane Sangarre, who had accompanied him to the Angara, urged him to put this plan in execution.

      Indeed, it was necessary to act without delay. The Russian troops from the government of Yakutsk were advancing towards Irkutsk. They had concentrated along the upper course of the Lena. In six days they would arrive. Therefore, before six days had passed, Irkutsk must be betrayed. Ogareff hesitated no longer.

      One evening, the 2d of October, a council of war was held in the grand saloon of the palace of the governor-general. This palace, standing at the end of Bolchaia Street, overlooked the river. From its windows could be seen the camp of the Tartars, and had the invaders possessed guns of wider range, they would have rendered the palace uninhabitable.

      The Grand Duke, General Voranzoff, the governor of the town, and the chief of the merchants, with several officers, had collected to determine upon various proposals.

      “Gentlemen,” said the Grand Duke, “you know our situation exactly. I have the firm hope that we shall be able to hold out until the arrival of the Yakutsk troops. We shall then be able to drive off these barbarian hordes, and it will not be my fault if they do not pay dearly for this invasion of the Muscovite territory.”

      “Your Highness knows that all the population of Irkutsk may be relied on,” said General Voranzoff.

      “Yes, general,” replied the Grand Duke, “and I do justice to their patriotism. Thanks to God, they have not yet been subjected to the horrors of epidemic and famine, and I have reason to hope that they will escape them; but I cannot admire their courage on the ramparts enough. You hear my words, Sir Merchant, and I beg you to repeat such to them.”

      “I thank your Highness in the name of the town,” answered the merchant chief. “May I ask you what is the most distant date when we may expect the relieving army?”

      “Six days at most, sir,” replied the Grand Duke. “A brave and clever messenger managed this morning to get into the town, and he told me that fifty thousand Russians under General Kisselef,
